FDTD全场散射,光..光源选的全场散射光源TFSF,用了Cross section分析组,得到的光谱图的纵坐标表示什么意思?它和反射率有什么关系?或者说怎么把得到的图像纵坐标转换成反射率?如图为查看Z2的光谱图。求大神告知
Now run the simulation, then plot the refractive index result. This result does apply the unfolding across the symmetry of boundaries so that we can see the full refractive index cross section. Now that we've seen an example of setting up the index monitor, here are some tips for using th...

科研小白,对散射光谱的本质都还不太懂,别说FDTD作图了。按照教程,在FDTD里设置cross section,然后模拟一波作出的结果我就蒙蔽了,横坐标是入射光波长,但这纵坐标是什么鬼?为什么论文里看到的是直接写着scattering(a.u),代表着什么?我只是照着论文先学一下它的模拟,做的是玻璃衬底上放硅柱,请大神赐教! 海子 高级...
吸收截面+散射截面 什么
涉及的内容:2D-FDTD、场监视器、cross-section分析组、matlab编程 等; 绘制了:散射截面随波长的关系、电场分布。 包含的文件截图: 详细描述: 如上图所示,用TM偏振的平面光照射一根无限长的介质纳米线,纳米线的半径为100 nm,折射率为2。本案例用 FDTD 模拟了400 ~ 800 nm波长范围内的光散射截面以及电场分布,并...
